More specifically, thetransverse aberration caused when the longest operation wavelength(e.g., 650 nm) and the shortest operation wavelength (e.g., 470 nm) passthrough the edge of the aperture can be used as the reference forevaluating performance.

For any surface of any lens, the profile curve length within theeffective half diameter affects the ability of the surface to correctaberration and differences between optical paths of light in differentfields of view. With longer profile curve length, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the profile curve length within the effective halfdiameter of any surface of any lens has to be controlled. The ratiobetween the profile curve length (ARS) within the effective halfdiameter of one surface and the thickness (TP) of the lens, which thesurface belonged to, on the optical axis (i.e., ARS/TP) has to beparticularly controlled. For example, the profile curve length of themaximum effective half diameter of the object-side surface of the firstlens is denoted by ARS11, the thickness of the first lens on the opticalaxis is TP1, and the ratio between these two parameters is ARS11/TP1;the profile curve length of the maximum effective half diameter of theimage-side surface of the first lens is denoted by ARS12, and the ratiobetween ARS12 and TP1 is ARS12/TP1.

For any surfaceof other lenses in the optical image capturing system, the ratio betweenthe profile curve length of the maximum effective half diameter thereofand the thickness of the lens which the surface belonged to is denotedin the same manner.

For any surface of any lens, the profile curve length within a half ofthe entrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityto correct aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half of the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half of the entrance pupil diameter (HEP) of one surfaceand the thickness (TP) of the lens, which the surface belonged to, onthe optical axis (i.e., ARE/TP) has to be particularly controlled. Forexample, the profile curve length of a half of the entrance pupildiameter (HEP) of the object-side surface of the first lens is denotedby ARE11, the thickness of the first lens on the optical axis is TP1,and the ratio between these two parameters is ARE11/TP1; the profilecurve length of a half of the entrance pupil diameter (HEP) of theimage-side surface of the first lens is denoted by ARE12, and the ratiobetween ARE12 and TP1 is ARE12/TP1. The profile curve length of a halfof the entrance pupil diameter (HEP) of the object-side surface of thesecond lens is denoted by ARE21, the thickness of the second lens on theoptical axis is TP2, and the ratio between these two parameters isARE21/TP2; the profile curve length of a half of the entrance pupildiameter (HEP) of the image-side surface of the second lens is denotedby ARE22, and the ratio between ARE22 and TP2 is ARE22/TP2. For anysurface of other lenses in the optical image capturing system, the ratiobetween the profile curve length of a half of the entrance pupildiameter (HEP) thereof and the thickness of the lens which the surfacebelonged to is denoted in the same manner.

In an embodiment, a height of the optical image capturing system (HOS)can be reduced if |f1|>|f7|.

In an embodiment, when |f2|+|f3|+|f4|+|f5|+|f6| and |f1|+|f7| of thelenses satisfy the aforementioned conditions, at least one lens amongthe second to the sixth lenses could have weak positive refractive poweror weak negative refractive power. Herein the weak refractive powermeans the absolute value of the focal length of one specific lens isgreater than 10. When at least one lens among the second to the sixthlenses has weak positive refractive power, it may share the positiverefractive power of the first lens, and on the contrary, when at leastone lens among the second to the sixth lenses has weak negativerefractive power, it may fine turn and correct the aberration of thesystem.

In an embodiment, the seventh lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size. Besides, the seventh lens can have at least aninflection point on at least a surface thereof, which may reduce anincident angle of the light of an off-axis field of view and correct theaberration of the off-axis field of view.

In an embodiment, the lenses of high Abbe number and the lenses of lowAbbe number are arranged in an interlaced arrangement that could behelpful for correction of aberration of the system.

An equation of aspheric surface is

z=ch ₂/[1+[1(k+1)c ² h ²]^(0.5) ]+A4h ⁴ +A6h ⁶ +A8h ⁸ +A10h ¹⁰ +A12h ¹²+A14h ¹⁴ +A16h ¹⁶ +A18h ¹⁸ +A20h ²+  (1)

where z is a depression of the aspheric surface; k is conic constant; cis reciprocal of the radius of curvature; and A4, A6, A8, A10, A12, A14,A16, A18, and A20 are high-order aspheric coefficients.

In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the system, and the glass lenses may control the thermal effectand enlarge the space for arrangement of the refractive power of thesystem. In addition, the opposite surfaces (object-side surface andimage-side surface) of the first to the seventh lenses could be asphericthat can obtain more control parameters to reduce aberration. The numberof aspheric glass lenses could be less than the conventional sphericalglass lenses, which is helpful for reduction of the height of thesystem.

When the lens has a convex surface, which means that the surface isconvex around a position, through which the optical axis passes, andwhen the lens has a concave surface, which means that the surface isconcave around a position, through which the optical axis passes.

The optical image capturing system of the present invention could beapplied in a dynamic focusing optical system. It is superior in thecorrection of aberration and high imaging quality so that it could beallied in lots of fields.

The optical image capturing system of the present invention couldfurther include a driving module to meet different demands, wherein thedriving module can be coupled with the lenses to move the lenses. Thedriving module can be a voice coil motor (VCM), which is used to movethe lens for focusing, or can be an optical image stabilization (OIS)component, which is used to lower the possibility of having the problemof image blurring which is caused by subtle movements of the lens whileshooting.

To meet different requirements, at least one lens among the first lensto the seventh lens of the optical image capturing system of the presentinvention can be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect can be achieved by coating on at leastone surface of the lens, or by using materials capable of filtering outshort waves to make the lens.

To meet different requirements, the image plane of the optical imagecapturing system in the present invention can be either flat or curved.If the image plane is curved (e.g., a sphere with a radius ofcurvature), the incidence angle required for focusing light on the imageplane can be decreased, which is not only helpful to shorten the lengthof the system (TTL), but also helpful to increase the relativeilluminance.

Third Embodiment

As shown in FIG. 3A and FIG. 3B, an optical image capturing system ofthe third embodiment of the present invention includes, along an opticalaxis from an object side to an image side, a first lens 310, a secondlens 320, a third lens 330, an aperture 300, a fourth lens 340, a fifthlens 350, a sixth lens 360, a seventh lens 370, an infrared rays filter380, an image plane 390, and an image sensor 392. FIG. 3C is atransverse aberration diagram at 0.7 field of view of the thirdembodiment of the present application.

The first lens 310 has negative refractive power and is made of glass.An object-side surface 312 thereof, which faces the object side, is aconvex surface, and an image-side surface 314 thereof, which faces theimage side, is a concave surface.

The second lens 320 has negative refractive power and is made ofplastic. An object-side surface 322 thereof, which faces the objectside, is a concave aspheric surface, and an image-side surface 324thereof, which faces the image side, is a concave aspheric surface.

The third lens 330 has positive refractive power and is made of plastic.An object-side surface 332 thereof, which faces the object side, is aconvex aspheric surface, and an image-side surface 334 thereof, whichfaces the image side, is a convex aspheric surface. The image-sidesurface 334 has an inflection point.

The fourth lens 340 has positive refractive power and is made ofplastic. An object-side surface 342, which faces the object side, is aconvex aspheric surface, and an image-side surface 344, which faces theimage side, is a convex aspheric surface. The object-side surface 342has an inflection point.

The fifth lens 350 has negative refractive power and is made of plastic.An object-side surface 352, which faces the object side, is a concaveaspheric surface, and an image-side surface 354, which faces the imageside, is a concave aspheric surface The object-side surface 352 has aninflection point.

The sixth lens 360 has positive refractive power and is made of plastic.An object-side surface 362, which faces the object side, is a convexsurface, and an image-side surface 364, which faces the image side, is aconvex surface. The image-side surface 364 has an inflection point.Whereby, incident angle of each field of view for the sixth lens can beeffectively adjusted to improve aberration.

The seventh lens 370 has positive refractive power and is made ofplastic. An object-side surface 372, which faces the object side, is aconvex surface, and an image-side surface 374, which faces the imageside, is a concave surface. It may help to shorten the back focal lengthto keep small in size. In addition, the object-side surface 372 has aninflection point, and the image-side surface 374 has two inflectionpoints, which may reduce an incident angle of the light of an off-axisfield of view and correct the aberration of the off-axis field of view.

The infrared rays filter 380 is made of glass and between the seventhlens 370 and the image plane 390. The infrared rays filter 390 gives nocontribution to the focal length of the system.

The parameters of the lenses of the third embodiment are listed in Table5 and Table 6.

Fourth Embodiment

As shown in FIG. 4A and FIG. 4B, an optical image capturing system 40 ofthe fourth embodiment of the present invention includes, along anoptical axis from an object side to an image side, a first lens 410, asecond lens 420, a third lens 430, an aperture 400, a fourth lens 440, afifth lens 450, a sixth lens 460, a seventh lens 470, an infrared raysfilter 480, an image plane 490, and an image sensor 492. FIG. 4C is atransverse aberration diagram at 0.7 field of view of the fourthembodiment of the present application.

The first lens 410 has negative refractive power and is made of glass.An object-side surface 412 thereof, which faces the object side, is aconvex surface, and an image-side surface 414 thereof, which faces theimage side, is a concave surface.

The second lens 420 has negative refractive power and is made ofplastic. An object-side surface 422 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 424thereof, which faces the image side, is a concave aspheric surface.

The third lens 430 has positive refractive power and is made of plastic.An object-side surface 432 thereof, which faces the object side, is aconvex aspheric surface, and an image-side surface 434 thereof, whichfaces the image side, is a convex aspheric surface. The object-sidesurface 432 has an inflection point.

The fourth lens 440 has positive refractive power and is made ofplastic. An object-side surface 442, which faces the object side, is aconvex aspheric surface, and an image-side surface 444, which faces theimage side, is a convex aspheric surface.

The fifth lens 450 has negative refractive power and is made of plastic.An object-side surface 452, which faces the object side, is a convexaspheric surface, and an image-side surface 454, which faces the imageside, is a concave aspheric surface. The object-side surface 452 has aninflection point.

The sixth lens 460 has positive refractive power and is made of plastic.An object-side surface 462, which faces the object side, is a convexsurface, and an image-side surface 464, which faces the image side, is aconcave surface. Whereby, incident angle of each field of view for thesixth lens can be effectively adjusted to improve aberration.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system ofthe sixth embodiment of the present invention includes, along an opticalaxis from an object side to an image side, a first lens 610, a secondlens 620, a third lens 630, an aperture 600, a fourth lens 640, a fifthlens 650, a seventh lens 660, a seventh lens 670, an infrared raysfilter 680, an image plane 690, and an image sensor 692. FIG. 6C is atransverse aberration diagram at 0.7 field of view of the sixthembodiment of the present application.

The first lens 610 has negative refractive power and is made of glass.An object-side surface 612, which faces the object side, is a convexsurface, and an image-side surface 614, which faces the image side, is aconcave surface.

The second lens 620 has negative refractive power and is made ofplastic. An object-side surface 622 thereof, which faces the objectside, is a concave aspheric surface, and an image-side surface 624thereof, which faces the image side, is a concave aspheric surface.

The third lens 630 has positive refractive power and is made of plastic.An object-side surface 632, which faces the object side, is a convexaspheric surface, and an image-side surface 634, which faces the imageside, is a convex aspheric surface. The image-side surface 634 has aninflection point.

The fourth lens 640 has positive refractive power and is made ofplastic. An object-side surface 642, which faces the object side, is aconvex aspheric surface, and an image-side surface 644, which faces theimage side, is a convex aspheric surface.

The fifth lens 650 has negative refractive power and is made of plastic.An object-side surface 652, which faces the object side, is a concaveaspheric surface, and an image-side surface 654, which faces the imageside, is a concave aspheric surface.

The sixth lens 660 can have positive refractive power and is made ofplastic. An object-side surface 662, which faces the object side, is aconvex surface, and an image-side surface 664, which faces the imageside, is a concave surface. Whereby, incident angle of each field ofview for the sixth lens 660 can be effectively adjusted to improveaberration.

The seventh lens 670 has positive refractive power and is made ofplastic. An object-side surface 672, which faces the object side, is aconvex surface, and an image-side surface 674, which faces the imageside, is a concave surface. The object-side surface 672 image-sidesurface 674 both have an inflection point. It may help to shorten theback focal length to keep small in size. In addition, it may reduce anincident angle of the light of an off-axis field of view and correct theaberration of the off-axis field of view.

The infrared rays filter 680 is made of glass and between the seventhlens 670 and the image plane 690. The infrared rays filter 680 gives nocontribution to the focal length of the system.

The parameters of the lenses of the sixth embodiment are listed in Table11 and Table 12.

Eighth Embodiment

As shown in FIG. 8A and FIG. 8B, an optical image capturing system ofthe eighth embodiment of the present invention includes, along anoptical axis from an object side to an image side, a first lens 810, asecond lens 820, a third lens 830, an aperture 800, a fourth lens 840, afifth lens 850, a seventh lens 860, a seventh lens 870, an infrared raysfilter 880, an image plane 890, and an image sensor 892. FIG. 8C is atransverse aberration diagram at 0.7 field of view of the eighthembodiment of the present application.

The first lens 810 has negative refractive power and is made of plastic.An object-side surface 812, which faces the object side, is a convexaspheric surface, and an image-side surface 814, which faces the imageside, is a concave aspheric surface. The object-side surface 812 and theimage-side surface 814 both have an inflection point.

The second lens 820 has negative refractive power and is made ofplastic. An object-side surface 822 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 824thereof, which faces the image side, is a concave aspheric surface. Theobject-side surface 822 and the image-side surface 824 both have aninflection point.

The third lens 830 has positive refractive power and is made of plastic.An object-side surface 832, which faces the object side, is a convexaspheric surface, and an image-side surface 834, which faces the imageside, is a convex aspheric surface. The object-side surface 832 and theimage-side surface 834 both have an inflection point.

The fourth lens 840 has positive refractive power and is made ofplastic. An object-side surface 842, which faces the object side, is aconvex aspheric surface, and an image-side surface 844, which faces theimage side, is a convex aspheric surface.

The sixth lens 860 can have positive refractive power and is made ofplastic. An object-side surface 862, which faces the object side, is aconcave surface, and an image-side surface 864, which faces the imageside, is a convex surface. The object-side surface 862 and theimage-side surface 864 both have an inflection point. Whereby, incidentangle of each field of view for the sixth lens 860 can be effectivelyadjusted to improve aberration.

The seventh lens 870 has positive refractive power and is made ofplastic. An object-side surface 872, which faces the object side, is aconvex surface, and an image-side surface 874, which faces the imageside, is a concave surface. The image-side surface 874 has an inflectionpoint. It may help to shorten the back focal length to keep small insize. In addition, it may reduce an incident angle of the light of anoff-axis field of view and correct the aberration of the off-axis fieldof view.

The infrared rays filter 880 is made of glass and between the seventhlens 870 and the image plane 890. The infrared rays filter 880 gives nocontribution to the focal length of the system.
